Question

Why is there water on a hockey field?

Answer 1

That is not a field, nor is that water... it is called ice.

Answer 2

The synthetic based hockey field (Astro turf) requires frequent watering, to provide for player comfort, hockey ball's bounce and friction control.

Answer 3

Water is there mainly to allow you to slide. It can slow the game down a little bit at the start, but if you have ever tried to dive on a dry pitch it is terrible carpet burn. By allowing you to slide, it decreases risk of knee and ankle injury- dry fields are like trying to stop and turn quickly on carpet- when you have studded shoes on, it is very difficult.  

Answer 4

Because over in India it is monsoon season, meaning it rains.
